For 2023, Apple is reportedly working on a larger 15-inch MacBook Air to join its Mac lineup. The new MacBook Air will feature the upcoming M3 chip, according to Bloomberg’s Mark Gurman. The 15-inch MacBook Air is expected to feature the same design as the current 13.6-inch model but with a larger display and longer battery life thanks to the efficiency of the M3 chip and the inclusion of a larger battery.

The possible 15-inch MacBook Air makes a lot of sense from a product line perspective (non pro machine with high portability but a larger screen). Where I disagree with Gurman is the possibility of the device getting an M3 chip. This is way too early. The rest of the product line is still on the just-released M2. When the Mac Pro finally makes the switch, then the M3 is a higher probability. In other words, I expect to see the 15-inch MacBook Air to get the same M2 chip as the current but smaller ones.
